Hi,

I live in Southern Minnesota, and we've already had two or three light
frosts. Is it too late to spray for dandelions? I'd really like to spray
this fall because I'd like things to look nice for my daughter's graduation
party next spring.

Thank you,

Weeds need to be actively growing for the weed killer to work. The
colder it is, the less effective the herbicide will be.

For where you are, I think it's too late, by about a month, maybe two.

Save the weed killer for the spring.

Have you had a -killing- frost yet?

Hello Randy,
I'd only guess it's late in the Minnesota growing season for post emergent
turfgrass weed control.

The good news is the dandelions are perhaps the easiest turfgrass weed to
control, even in the spring.

Anything with 24D will wipe them out. (oh that's not PC?)

I put on pre-emergent herbicide in the spring and a broadleaf weedkiller in
early summer. That works against crabgrass and dandelions, the two biggest
problems in my lawn.

I agree. Here in NJ I would say yes, but that far north it's
probably not going to be that effective or worth it. The amount of
herbicide and/or the number of applications required goes up as the
temps go down. Even Roundup takes a higher concentration and longer
to kill plants when they are barely growing due to lower temps.

Ok, thank you everyone for your help. The temps dropped down to the low 20s
over the weekend, so I guess I'll have to wait for next spring. (That's
eight months from now in Minnesota!!! Lol!)
